Galactic pulsar wind nebulae are suitable targets for studying relativistic plasmas because they radiate in all energy ranges, and a number of PWNe are close enough that their spectra, dynamics and morphology can be resolved in great detail. Pulsar wind nebulae often exhibit a jet-torus morphology in X-rays, unless distorted by very strong external flow. Typically, nebulae form a single...

54. On the statistical properties of the widths of the mean radio pulsar profiles

Using the data from FAST and MeerKAT radio telescope surveys, we carried out a detailed statistical analysis of the distributions of the observed widths of mean radio pulsar profiles. The availability of the high-quality polarization data made it possible to separately consider mean profiles formed by the ordinary (O) and extraordinary (X) orthogonal polarization modes. We performed an...

New surveys by the FAST and MeerKAT observatories have enabled, for the first time, a robust statistical study of orthogonal pulsars using large homogeneous samples. These objects, with magnetic axis nearly perpendicular to the rotation axis, are particularly sensitive to magnetospheric physics and serve as a key test for neutron star evolution models. We show that the statistical properties...
